Question

The number of the corner in a cone is
1) 1
2) 2
3) 3
4) None of these

Answer 1

Hint: Find out the shape of the cone. From the shape of the cone observe the faces, corners and edges in the cone. Write the number of faces, corners and edges present in the cone. Then the final answer will be the number of corners in the cone.

Complete step by step solution:

A cone is a 3D figure that has a circular base which is a flat surface and then it tapers smoothly from a flat base to a point called vertex or apex.

As we know that a cone has a curved surface, one edge but no corners.
Also, the cone is a solid figure with two surfaces.
And the corner is defined as the meeting point of two edges in any figure.
But shapes like cones, cylinders and spheres do not have any flat sides, which will meet to form a corner.
Also, the cone has only one edge that is also known as the circular edge.
So, there is no meeting point of two edges.
Therefore, a cone has no corner.
Hence, option D is the correct answer.

Note:- The point where the cone tapers from a flat base is known as the Apex of the cone. The corner is formed when edges meet, but cones have a single circular edge. A cone has a round and a flat surface.
